Invitation for contribution to COWCLIP Phase 2

The Coordinated Ocean Wave Climate Project (COWCLIP), supported by JCOMM and WCRP, aims to generate wave climate projections (ultimately of global extent) and aid comprehensive assessments of their cascading uncertainty. Based on the discussion at the first COWCLIP workshop in Geneva (April, 2011;, the inter-comparison of the first community ensemble of global wave climate projections (COWCLIP Phase 1) is now completed and the results are available online.

The wave community is now invited to contribute to the COWCLIP Phase 2 intercomparison study (ongoing until November 2013): It aims to quantify the source of variance between available studies, through a more designed approach using CMIP5 derived datasets.

Training on wave and storm surge modelling


 JCOMM, in collaboration with WMO Tropical Cyclone Programme (TCP), has successfully conducted the Eighth JCOMM-TCP Workshop on Storm Surge and Wave Forecasting (SSW-8) in Nairobi, Kenya, from 19 to 23 November 2012. This was the first training opportunity for South and East African countries on wave and surge modelling. Highly qualified participants from Kenya, Madagascar, Mauritius, Mozambique, Namibia, Seychelles, South Africa and Tanzania enjoyed 5-day training programme provided by the experts from France (La Reunion), India, Japan, Kenya, USA and the WMO Secretariat. Two Members of the JCOMM Expert Team on Waves and Coastal Hazards Forecasting Systems (ETWCH) - Drs Hendrik Tolman (USA) and Nadao Kohno (Japan) - contributed to this event as lecturers.

International workshop on seasonal to decadal prediction

services access

The WCRP Working Groups on Seasonal to Interannual Prediction (WGSIP) and the Working Group on Climate Modelling (WGCM) are organizing an international workshop on seasonal and decadal prediction, in Toulouse, France, from 13 to 16 May 2013. Please find details at the workshop web site.  

On a related note: Noting its mandate in coordinating operational ocean modelling/forecasting systems, JCOMM at its 4th session (2012) agreed to pursue developing a coordination framework for operational coupled seasonal climate forecast systems. The focus of the JCOMM contribution is on the ocean component of the system, applications of ocean observations and standardization of ocean data for use in ocean analyses and seasonal forecast systems. Further details can be found in the 2012-2017 SFSPA Workplan


WMO/CLIOTOP Workshop on Climate and Fisheries


JCOMM and the WMO Commission for Agricultural Meteorology (CAgM) are committed to assisting future sustainable management of fisheries by improving access to and use of weather and climate data and products relevant to fisheries management. Toward this goal, a Climate and Fisheries workshop will be held as part of the 2nd CLIOTOP Open Science Symposium in Noumea, New Caledonia, 11-15 February 2013. Please see details at the workshop web site

The Joint CAgM/JCOMM Task Team on Weather, Climate and Fisheries (TT-WCF) will lead the WMO contribution to this Workshop.
